MECHANICAL MGVEMENT.

1., ZSCIPZCAZION forming part of Letters Patent No. 303,791 dated August 19, 138%,

(No model.)

550 all whom it may concern:

Be it known that 1, CHARLES Binznniinn, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Mechanical Movements, of which the following is a specification.

This invention relates to means for converting oscillating or reciprocating motion-into rotary motion; and it consists in the novel features of construction hereinafter described, whereby the desired purpose is accomplished.

In the drawings, Figure 1 shows a plan view of my movement. Fig. 2 is a sectional side view thereof. Fig. 3 is a front view thereof. Fig. t is a modification.

Si milar letters indicate corresponding parts.

The movement is shown in the drawings as applied to a boator vessel for operating the propelling device; but of course my movement is applicable to other purposes.

The letters A designate standards, in which are mounted a driving-shalt, 1), adapted to support the driving mechanism, and a main shalt, E.

On the driving shaft D are mounted cogwheels G- and chain-whecls I, and on the main shaft E are mounted cog-wheels J, gearing with the cog-wheels G, and chain-wheels K, con meeting with the chain-wheels I by means of chains L. The cog-wheels J and chain-wheels K on the main shaft are fixed, and the ehaiir wheels I are loose.

The device as thus far described bears a resemblance to the device described by me in my United States Letters Patent No. 298,160, dated May 6, 188$. In the specification of said patent, however, the cog-wheels G are described as being fixed on the drivingshaft, which is an inconvenience in case any of such cog-wheels G-arcbroken orout of order, as then it may become necessary that the entire driv' ing-sha'ft be taken out. In the device set forth in this application the cog-wheels G are loose upon the driving-shaft 1), and any cog-wheel G which is deranged or inoperative can readily be removed and repaired or replaced by another.

To the cog-wheels G are secured ratchetwheels G, while to the chain-wheels I are socured ratchet-wheels i, The ratcheis of the wheels G face in opposite directions from the ratchcts of the wheels 1. t

On the drivingshaft it are mounted levers N, which, in the example in the drawings, are hand-levers. (in said lovers are pawls 0 0, in the proper position to engage, respectively, the ratchet-wheels, so that if an oscillating or reciprocating motion is imparted to these lc- Vers N a rotary motion is imparted to the cogwhecls G, and also to the chain-wheels I; but the motion of the chain-wheels I is in a direc tion opposite to that of the cog-wheels G. The motion of the cog-wheels G and chain-wheels I is imparted to the main shaft E; but as the cog-wheels G impart a rotary mot-ion to the main shaft E in a direction opposite to that of the cog-wheels G, while the chaiirwheels I inipart a rotary motion to the main shaft E in the same direction as that of'thc chain-wheels I, the actuations of the levers H will cause the main shaft E to continuously turn in the same direction.

0n the main shaft E is feathered a sleeve,

'1 which turns with the main shaft but is capablc of longitudinal motion thereon. On said sleeve 1 are mounted bevel-wheels P and Q, and by causing the bevel-wheel P to gear with the l'icvel-wheel. It, mounted on the actuatingshaft S, said actuating-shaft S will be caused to turn in one direction, and by causing the bevehwheel Q, to gear with the bcvel-whce1 1% the shaft S will be caused to turn in the op posite direction: By throwing both the bevelwheels 1 and Q out of gear the actuating-shaft S will not be operated through the main shaft E. The actuating-shaft S may be used to act-uate any desired deviceas, for example, a propeller, F. The levers N may be connected by rods or pitmen to supplemental levers N, so as to increase the facilities for applying power. A lever, U, may serve to throw the bevel-wheels P and Q, into or out of gear, and said lever U may be held in any desired position by the dctent-reccsses aa.

The usefulness of my device-for example, as a propelleris illustrated by the fact that it enables the person operating to face in the direction the boat is moving, allowing the feet to operate the lever V, operating the rudder IOO A screw-washer, \V, can be screwed down onto the lever V and hold it in any desired position.

Of course my device may be modified in construction without departing from my inventionas, for example, the driving-shaft D, in stead of running across the entire apparatus, may be formed in two parts or sections, independent of one another, and each section of sufficient length to support a lever, N, and wheels G and I, and instead of the chain L and chain-wheels I K three cog-wheels, I IQ I*, may be used, the wheel 1* being fast to the ratchet-wheel I, the wheel K being firmly mounted on the main shaft E, and the wheel 1 being intermediate between the two, so that when the ratchet-wheel I is turned the shaft E will turn in the same direction, as shown in Fig. 4. It is also'to be noticed that one lever, N, will serve to actuate the main shaft E; but I prefer two or more levers as furnishing ready means for applying any desired amount of power..

WVhat I claim as new, and desire to secure by Letters Patent, is A l. The combination, substantially as hereinbefore described, with the drivingshaft and the main shaft, of two ratchet-wheels, both loosely mounted on the driving-shaft, the os cillating lever mounted on the driving-shaft intermediate between the ratchet-wheels, the pawls secured to this lever and adapted to engage the ratchet-wheels, the cogwheels G J, for transmitting motion from one of the ratchetwheels to the main shaft, and the chains and chain-wheels or equivalent devices for transmitting motion from the other ratchet-wheel to the main shaft.

one ratchet-wheel near each end of the drivf ing-shaft to the main shaft, and the chains and chain-wheels or equivalent devices for transmitting motion from the other ratchet-wheel near each end of the d riving-shaft to the main shaft.

8. The combination, substantially as hereinbcfore described, with the drivingshaft and the main shaft, of cog-wheels G J, gearing with one another, chain wheels I K, or equiva lent evices, ratchet-wheels G I, lever N, engaging with said ratchet-wheels, and gearwheels I Q, adapted to engage alternately with an actuating-pinion, R.

4. The combination, substantially as hereinbefore described, with the drivingshaft and the main shaft, of cog-wheels G J, gearing with one'another, chain-wheels I K, or equivalent devices, ratchet-whcels G I, lever N, engaging with said ratchetwvheels, and gearwheels I Q, provided with means for throw ing said wheels I and Q into and out of gear with an actuating pinion or wheel, R.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
